How to Install a New Garbage Disposal: A Step-by-Step DIY Guide · Step 2 of 4
In this video
To remove the old disposal unit, use the disposal tool (or a large Phillips screwdriver) to turn the mounting ring counter-clockwise. Insert the tool into one of the lugs on the lower mounting ring and apply firm pressure to rotate it. This will disengage the ring from the ramps on the upper sink flange, allowing the disposal to drop down. Be sure to support the weight of the disposal with your other hand as it comes loose.
Goal: Remove old disposal from sink mount
- The garbage disposal is heavy. Make sure you have a firm grip on it to prevent it from falling and causing injury or damage.

FAQs
What are the most crucial safety steps I need to take before starting to install a new garbage disposal?
Always start by turning off the power to the disposal at your home's circuit breaker and confirming it's off with a non-contact voltage tester. Additionally, shut off both the hot and cold water supply lines under the sink to prevent any accidental leaks during the process.
The project is listed as 'beginner' with a 4-hour estimate; what might make it take longer or be more challenging for a novice?
Old, corroded plumbing can make removing the old unit difficult if bolts are seized or pipes are brittle. Ensuring a watertight seal when installing the new flange and correctly aligning the drain pipes can also be tricky for beginners, potentially extending the project duration.
What's the most common mistake beginners make when installing the new garbage disposal flange, and how can I avoid it?
A common mistake is not applying enough plumber's putty or not tightening the flange assembly evenly, leading to leaks around the sink opening. Apply a generous, even bead of putty around the flange's rim and tighten the mounting screws incrementally and alternately to ensure uniform pressure.
Are there any specific tools or materials not listed that might make this beginner-level project easier or safer?
While not explicitly listed, a non-contact voltage tester is crucial for safety to confirm power is off. Plumber's putty is essential for creating a watertight seal for the new flange, and a flashlight or headlamp will greatly improve visibility in the cramped under-sink area.
